To all whom it may concern:

Be .it known thatI, JAMES A. GRAY, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inApparatus for Cutting and Applying Ring-Liners, of which the followingis a specification.-

The present invention relates to an apparatus for the cutting from adisk blank an annular or ring liner for'use in applying to thecircumferential flange of can ends or covers, the object being by asingle operation of the cutting mechanism to properly trimthe diskblank, to sever therefrom the de sired annulus or ringliner'and at thesame time remove the core-section thereof, thereby accomplishing by asingle acting punch means that which heretofore has required the actionoftwo punches to successfully carry out. v

Usually, in the cutting of ring liners. for

the flange of can ends or heads. a traveling web is emploved'from whichthe annulus to be removed or severed is first presented to the action ofa punch for removing there. from the central core. andth-ereafter thesaid web is acted on by a second punch or die of a diameter slightlvlarger than that of the first punch or die for the removal therefrom ofthe annulus or ring liner. It

is the employment of this intermittent-- traveling web that the presentmachine successfully overcomes, permitting the utilization of diskblanks for the cutting of the ring liner therefrom and bV so doingsimplifying. the construction of the apparatus,

. reducing the expense incident thereto to a minimum and at the sametime materially increasing the output of ring liners- To comprehend theinvention, reference should lie had to the accompany ng sheets ofdrawings, wherein Figure 1 is a side view inelevation-of the improvedcutting apparatus. illustrating the same as applied to means forreceiving the cut annulus or ring liners and can ends or covers and forapplying the'said liners to the flange of the can ends or covers. alsodisclosing the means for actuating the various working parts of the saidcutting apparatus.

the feed mechanism for the diskblank heing disclosed. Fig. 2 is alongitud nal sectional view taken through the reciprocating die punchmechanism and the stationary associated' die, disclosing in part sectionone of the pocketsof a rotai vdisk carrier for receiving'the cut annulusor ring liners, the means for feeding the cut annulus therein, and thereciprocating 'plungers working within the said pocket for applying thesaid annulus to the flange of a can end or cover, saidview alsoillustrating the manner ofv disposing of the central core removed fromthe disk blank during the operation of cuttingthe annulus or ring linertherefrom. Fig. '3 is a plan .view disclosing the sizes and positions ofthe centercore, annulus or ring liner and the trimmed waste relative tothe disk blank from which the annulus or ring liner is to be severed.Fig-i is a plan view partlj in section of the stationarv die. thereciprocating die punch and the .parts associated therewith, the samebeing tracting means partly in its inward posi-- tion. Fig. l isavertical pai'tsectional view taken on the irregular line Fig. 1 of thedrawings. disclosing the picker 'or extracting means as'having removedand re leased for discharge the trimmed waste material of the blank.Fig. 8 is -a view similar to Fig. 1'' of thedrawings, illustrating theposition of the picker or extracting means as about to engage the .wasteof the blank for removal. Fig. 9 is a perspective view of the trip meansforac'tuating the nipper finger or aw of the'picker or extracting means.Fig. 10 is an enlarged detail part sectional view ofthe mechanismforremoving the disk 'blanks successively from the stack within the holdeand for delivering the same to the feed runway for the posi; tioningthereof relative to the cutting mechanism. Fig. 11 is a plan, view ofthe parts disclosed bv Fig. 10 of the drawings. Fig. 12 is a verticalsectional view taken on line y --2 Fig. 10 of thedrawings.

- In the drawings, the numeral 1 is used to designate any suitableformof a supportingfraine capable. of sustaining the Working throughwhich respectively the cut annulus parts of the apparatus, which frameis provided with a bed plate 2. Within the frame 1 and secured on alongitudinal shaft 3 working in bearings 3 is situated a verticallydisposed carrier disk 4, the said disk.

, volves, and during the rotation of said carrier disk the plungers-6and 6 are moved toward andfrom each other for applying the hereinafterdescribed cut ring liner onto the flange of a can end or cover heldtherein, Figs. and 1 and 2 of the drawings.

Each of the circumferential seats 5 of the carrier disk' lis intersectedby the spaced segmental peripheral openings 11 and 12,

or ring liners and the can. ends or covers are delivered intd the saidseats 5 in spaced relationto each other between the opposing faces ofthe plungers 6 and 6, the can ends, heads or covers 13 being deliveredinto the seats of the disk carrier through the opening 12 in 'glny.suitable manner.

thebed 2 and within a longitudinal guide-way 14 thereof works areciprocating slide 14 carrying at its inner endqtwo concentric diepunches 15' and 15, there being interposed between said punches alongitudinally movable die ring 16, which die ring registers with theopposing stationary die ring 17 held to the ring 17 of the cylindricalmagazine 18, when the reciprocating slide- 14 carrying the die punchesis moved inward its full distance. The stationary die ring 17 isembraced by the follower ring 18' held to the fixed base ring 17 by thecollar 19, the said follower ring being normally held outwardly pressedby the springs 19 interposed between the base ring 17 and the bottomface'of the follower-ring, Figs. 2 and 4 of the drawings.

On a bracket 2' upwardly proiecting from the bed 2 is mounted atoneiside of but adjacent to the punch mechanism, a holder 20 fo thestack of ho zontally disposed fibrous d sks 21 from which the annulus orring liners are to be cut1'.Figs. 1, 10, 11.and 12 of the drawings. Theholder 20 is an open bottom one, the st ck of disks 21 resting on theshelves or ledges 22 thereof, and the same are removed successively fromwithin the holder by the hereinafter described sucker-arm. outwardlyprojecting from a rock-shaft 20". This shaft works within a suitablebearing and carries at one end a;

pinion 21, which meshes with a bevel gear action by the movement of theshaft 20 is a it sucke; arm 31, which is connected by an air connection32; to suitable suction means. As the arm 31 isthrown upwardly againstthe under exposed face of the lowermost disk of the stack of disks heldwithin the holder 20, the air suction causes the same to adhere firmlyto the said sucker arm, so that when the arm 31 is lowered or swungdownwardly,

the lowermost disk of the'stack *of disks 1s removed from within theholder 20 and delivered into the vertically disposed feed chute 32. Theair suction is destroyed as the arm- 31 reaches its lowermost position,so as to release the removed disk, said air connection being broken bythe port a in'its hinged connection moving out of registry with the'openport b (Fig. 11), thus destroying the air suction through the hollowsucker arm 31-and allowing air to enter between the disk and the edge'ofthe sucker, and the removed disk blank to fall from the open endthereof. The disks 21 are thus successively removed from the holder anddelivered into the feed chute 32 and by said chute discharged into thesemi-circular seat 33 for positioning between the faces of thereciprocating die punch and the fixed die,

being held thereto against lateral displacement by the weight of thelight hinged holder 33Figs. 7 and 8 of the drawings. At the same timethe deposited disk is prevented from falling from within itsseat bymeans of the laterally movable slides 34rand 34, which are movedinwardly and outwardly during the reciprocating movement of the slide 14by means of the horizontally swinging fulcrumed arms 35, suitablyconnected at their forward ends to said slides.

The slide 14 has reciprocating motion inf-st parted thereto from thedrive shaft 2s'by means of the crank connection 14 Figs; 1 and 4 of thedrawings. By reference to Fig.

' 1 of the drawings, it will be noted that the motion of the drive shaft28 is transmitted is forced against the fixed die 17; while theconcentric punches 15 and l5 mov ng .'in,

to the shaft for actuating the earlier disk 4: through the medium of theintermeshing gears 37 and 37, the' gear 37' imparting Jmotion to a crossshaft 38 carrying a worm 38 which meshes with a worm gear 39 on theshaft- 3', the construction of the worm-' 38being such as to impartintermittent-rotation or movement to the 'worm gear 39.

Referring to Figs. 2, 4 and 5 of the drawings, it will be noted that thedie ring 16 is provided. with a.series of rearwardly extend- 1ng-pins16, which extend through bores" 16' in the circular shoulder 16 of theslide plunge-r 1-1, said pins bearing against. an

workin 'within 'uid'e' bearin s 17 u wardl a a a f y.

projecting from the bed 2.

The-drive shaft 28 is driven in any suitable manner and on thef-n'wardstroke of the slide plunger-.14 with the disk blank 21positioned as in Fig; 4 of the drawings, the

arms 35 are actuated to move outwardly the slides or slide. plates 34 34and the disk wardly beyond the peripheral edge of the said die ring17fcut or sei 'e-r from the disk blank 21 the. central core A, theannulusor ring liner B and the waste ring or trimming C, the cut annulus\or ring liner beii'ig lheld between the opposing faces of'the therings- 16 and '17; during which cutting actionthe follower ring 18giving inwardly, tl1e cen'- tral core A is forced into] the die ring 17by the cutting punch 15 for gradual delivery into the magazineiS by theaccumulation; of core pieces. On thereturn stroke of the sa dreci-prrcating shde plunger. the waste rin or trimmin C of the cut diskblank is forced from off the fstationa iry die ring 17 by the action'ofthe spring follower ls'j while the cut annulusjoraring lineriB- adahering to the faces of the' die punches l:" -15-- and the die ring l6 is"carried outward beyond the scat and in line with the d scha ge opening33?, when the eiector ring 17 act1ng against the spring-held pins-l7-gradually mores the die" ring 16 outwardly toforce the cut annulus'orringliner B clear of the die punches 15 and 15. permitting the same tofall through the outlet opening 33 to within the sphere of the transvesely horizontally dis sed feed rollers 40Figs. 2 and of the dra lags.The said feed rolls are mounted on the parallel shafts 40'-41,'

driven by the inter-meshing gears 42, rotary motion being imparted tothe shaft 41 froinj Lhe driven shaft 38 by the drive belt '42 workingover the belt. pulleys 43-43 mounted on the shaft 4i andrespectively,Fig. 1 rollers 40 deliver the cutannulus or ring of thedrawings. ,The feed be disposed of. and for this purpose there isprovided a reciprocating nipper or extracting device,icomprising in thepresent case an arm 23 depending from the rockershaft 23'Fig. 7 of thedrawings.- This arm is inwardly curved at its lower extremity and siidcurved extension 24: at its end has pivoted thereto a. spring heldnipper jaw ES -Figs. 4; 6, 7 and 8- of'the drawings.

The-lower end of the swinging arm 23 is supported by the curved bracket26 laterally projecting from the frame bedl2, and as the said arm isthrown inwardly the tail extension 25' of the nipper jaw 25"" rides ontheincllined face of a pivoted, cam 27, for gradually throwing thetailextension 25" inwardly to open the jaw 25 so as to' permit offthe saidjaw and the extreme end portion of the extension 24 to embrace theperipheral edge" of thewaste ring 0, Figs. 6 and 8 of the drawings. Thelip on the follower 18 has a cut out portion, as shown in Figs (i'and 7,to allow of the described action of thenip'per.v The tail extension 25"moving oil of or out of contact with the cam ,27 on the arm 23 beingswung inward its full distance, thepressure of the spring 28 thienexerts itself to force outwardly the tail ex ension25 to close thenipper 25" to clamp tie \aste ring C, while at the same time the spring29" acting against the cam 27 wingslits free inner end outwardly toclear he. depending section of -the tail extension of the nipper jaw.fith the waste ring \or material" C thus clampedy, the saine is removedand withdrawn from kits seatduringthe outward throw of. the arm2 3 being'30 carried until 'the depending section of thetail extension of thenipper jaw engages with and rides againon .the inner face of thecam-bracket 26-" {Fig.lhwrhen the said jaw is opened and the waste'ringCreleased for-deposit at any suitable place 1' Fig.7 of the. drawings.During this removal of the waste ring or trimmed portion C of thedisk21, the pi"-' oted holder or retaining guard 33' gives to the'n'essure exerted thereon, swinging upwardly to permit ofthe tr mmedportion C being withdrawn. As the arm 2.3 swings outwardlyitsfulhdistance the depending section of the {tail extension 25 of thenipper j aw moves off or out of contact with the inner face of the cam.27?, permitting the said cam to. return to normal position.

The core sections A whichaccumulate w? thin the magazine are removedtherefrom aud ted into a machine similar to the one,

- die plunger, of concentric die'punches carherein described and fromeach of which is cut an annulus or ring liner for use in connection withcan ends or covers of less di ameter than the ones to which the presentannulus or ring liner is to be applied.

The working stroke of the cutting mechanism, the action of the-feedmeans for sue cessively delivering disk blanks thereto, the removal ofthe waste material, the feeding of the cut annulus or ring liner to themechanism for applying the same to the flange ofcan ends'or covers areso regulated with respect tov each other, that the various de-' scribedactions successively come into 'play at predetermined moments, each partperforming its desired'work at the proper moment with respect to theother workingparts of the apparatus, thereby constituting an automaticmachine for the cutting of an annulus o r ring-liner from fed di'skblanks'by a single stroke ofthe die'punch mechanism.

By the described apparatus, the necessity for employing an endless webfor the cutting therefrom of the ring liners is obviated, equally so thecomplex mechanism .for controlling and regulating the feed of such a webis.dispensed with, .and the cutting and feeding of the ring liners isperformed with greater speed and accuracy than possible where acontinuous traveling Web is employed. J

It will be understood that the expression ring liner is not limited toan annulus, but merely to designate a cut liner of proper shape toconform to the flange of the can end or cover to which it is to beapplied, hence the term disk blank as herein employed is -meant toexpress a blank. of suitable shape from which the desired liner is to becut.

The present invention is not limited to the details of working parts asherein shown and described, for, these may be varied and modifiedwithout departing from the nature and spirit of the invention, and,therefore, I do not wish tobe understood as confining myself to i thedisclosed arrangement of working parts, but, on the contrary, desire tocover as far as theart will permitfthe combination of working featuresfor carrying out the described opera'tions.
